Why bother with digital systems? Digital sistems can process information a lot easier than analog sistems Digital computer is much more skilful than the analog computer Is there an analog computer, too? (Yes! It can take derivative, integral and do other operations)

14
Boolean Algebra Basic Operations AND OR NOT Gates are used for these operations

36
Logic Circuits Combinational Logic: output is determined by inputs only Sequential Logic: output depends on the inputs and history it contains some memory device to remember the past

Logic Systems and Gates I hope this presentation gave you a glimpse of the logic systems and digital circuits. You will have plenty of experience with digital circuits in Digital Systems I, II and Lab courses. End of the presentation
